Description

Technical Field

[0001] The utility model relates to the technical field of strip cutting machines, in particular to an equidistant cutting rubber strip cutting machine. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external forces, and can return to its original state after removing the external forces. During the manufacturing process of rubber products, in order to more reasonably and effectively carry out batch production of rubber products, it is often necessary to control the materials used for rubber products. Therefore, after the rubber mixing process, the processed rubber needs to be cut into strips so that its size and weight meet the requirements of subsequent production.

[0003] At the present stage, the rubber strip cutting machine places the rubber on the cutting table and conveys the rubber to the cutting openings of the upper cutter and the lower cutter through two rotating wheels for cutting;

[0004] Through long-term observation, when some rubber is cut on the feeding table, sometimes the rubber gets stuck on the feeding table due to excessive resistance of the feeding table. Moreover, the cutting blades of the traditional rubber strip cutting machine are fixed and cannot adjust the width, resulting in the inability to change the width of the rubber during the processing and cutting of the rubber, and the practicability is relatively low. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an equidistant cutting rubber strip cutting machine, which overcomes the deficiencies of the prior art and effectively solves the problems that sometimes the rubber gets stuck on the feeding table due to excessive resistance of the feeding table in the prior art, and the cutting blades of the traditional rubber strip cutting machine are fixed and cannot adjust the width.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An equidistant cutting rubber strip cutting machine includes a support mechanism and a cutting mechanism. The support mechanism includes a bottom shell, a baffle fixed to the top of the bottom shell, fixing blocks fixed to both ends of the top of the baffle, a lead screw rotatably connected between the two fixing blocks, a push plate screwed on the outer wall of the lead screw, and a first push rod motor fixed to the inner wall of one end of the bottom shell. The cutting mechanism includes a movable plate, connecting plates fixed to both sides of the outer wall of one end of the movable plate, rollers rotatably connected at equal distances between the two connecting plates, a bracket fixed to the top of one of the connecting plates, a fixing plate fixed to the outer wall of one side of the bracket, a third push rod motor fixed to the bottom of the fixing plate, and an upper cutter fixed to the bottom end of the third push rod motor.

[0008] By placing a rubber sheet on top of the rotating roller, as the second push rod motor extends downward, the pressing roller is driven to approach the rubber sheet below, enabling the pressing roller to abut against the top of the rubber sheet. The pressing roller is rotated by the driving motor, and in cooperation with the rotating roller at the bottom of the rubber sheet, the rubber sheet is conveyed. One end of the rubber sheet abuts against the baffle and stops. The third push rod motor extends downward to drive the upper cutter and the lower cutter to cooperate to cut the rubber sheet. After cutting is completed, the servo motor drives the lead screw to rotate, and the rotating lead screw drives the screwed push plate to move along the length of the baffle in the reverse direction, pushing out the cut rubber strip.

[0009] Preferably, one end of the lead screw is connected to a servo motor, and the servo motor is installed on the outer wall of one of the fixed blocks.

[0010] The output shaft of the servo motor drives the lead screw to rotate.

[0011] Preferably, the bottom of the push plate forms a sliding fit with the movable plate, and the push plate forms a sliding fit with the baffle.

[0012] The rotating lead screw drives the screwed push plate to move along the length of the baffle in the reverse direction.

[0013] Preferably, the cutting mechanism forms a sliding fit with the bottom shell, and the movable plate is fixedly connected to one end of the first push rod motor.

[0014] By the telescopic movement of the first push rod motor, the cutting mechanism is adjusted in position within the bottom shell, and the distance between the upper cutter and the baffle is adjusted, enabling the adjustment of the width of rubber cutting.

[0015] Preferably, a lower cutter is fixed between the two connecting plates, and the lower cutter is located directly below the upper cutter.

[0016] The lower cutter and the upper cutter cooperate with each other to complete the cutting operation.

[0017] Preferably, a second push rod motor is fixed to the inner wall of the top of the bracket, and a connecting frame is fixed to the bottom end of the second push rod motor. The inner walls at both ends of the connecting frame are rotatably connected to a pressing roller, and one end of the pressing roller is connected to a driving motor installed on the outer wall of the connecting frame.

[0018] By the telescopic movement of the second push rod motor, the position of the pressing roller and the rubber sheet below is adjusted, enabling the pressing roller to abut against the top of the rubber sheet. The pressing roller is rotated by the driving motor, and in cooperation with the rotating roller at the bottom of the rubber sheet, the rubber sheet is conveyed.

[0019] The beneficial effects of the present utility model are:

[0020] By placing a rubber sheet on the top of a rotating roller, the downward extension of the second push rod motor drives the pressure roller to abut against the top of the rubber sheet. The driving motor drives the pressure roller to rotate to convey the rubber sheet. The third push rod motor extends downward to drive the upper cutter and the lower cutter to cooperate to cut the rubber sheet. After cutting, the servo motor drives the push plate to move along the length of the baffle in the reverse direction to push out the cut rubber strip, effectively solving the problem in the prior art that sometimes the rubber gets stuck on the feeding table due to excessive resistance of the feeding table, and the problem that the cutting blades of traditional rubber strip cutting machines are fixed and the width cannot be adjusted.
